Many players do the same shot over and over against varying incoming balls, whether they are ready for the shot or not. For example, loopers might loop hard against any block to the forehand, even if rushed, off balance or not in position. Or they might loop a serve at the same speed over and over, regardless of whether they are sure they have read the serve properly. Instead, learn to slow down some shots, or choose a more controlled shot, if you are not really set for the shot (i.e. rushed, off balance, out of position or not sure of the spin).
